ECM File Corrupt From My Truck to Autocal

[SSSilverado23]

I recently sent my info to Justin (datalog, ecm file, transmission file) to get a custom tune done. The ECM file keeps downloading corrupt. It dowloads fine to the autocal from the truck but i emailed the file 2 different times to Justin and he says its corrupt. I unplugged my radio so my aftermarket stereo wouldnt interefere and it still happened. Anyone else have this problem? The transmission file was fine so im not sure why the ecm file is not downloading clean. Any help is appreciated.

 

In the scan and tune software it says "Checksum Invalid"

I think I had something similar last year. I think it was the firmware for the efilive box. You may want to ask Justin about the firmware.

What was the fix? It says in the scan and tune software "invalid Checksum"

I have been on large doses of narcotics for pain for the last few years, about the thing I can always recall is that my memory sucks. There was an update to the software I think. On Blackbears site there is a section about how to use the autocal, and it shows how to make sure you have the correct version of software I think. Maybe this will remind someone else and they can recall the fix for you.
